Docs/admin-guide/mm/damon/usage: describe the rules of sysfs region directories
Patch series "Docs/admin-buide/mm/damon/usage: minor fixes". DAMON usage document contains an unclear description and a wrong usage example. This patchset fixes the two minor problems. This patch (of 2): Target region directories of DAMON sysfs interface should contain no overlap and sorted by the address, but not clearly documented. Actually, a user had an issue[1] due to the poor documentation. Add clear description of it on the usage document.
